 * SYSTEM:    KVM
 * SUBSYSTEM: Native function interface
 * FILE:      native.h
 * OVERVIEW:  This file contains the definitions of native functions
 *            needed by the Java Virtual Machine. The implementation
 *            is _not_ based on JNI (Java Native Interface),
 *            because JNI seems too expensive for small devices.
